Abstract

A device for administering powdered substances into deep-seated cavities of an organism includes a sprayer of powdered substances, a conveying line including a drainage pipe and a catheter, a hollow cylindrical body divided by a diametral partition and a cover, and a first sleeve positioned in the diametral partition and a second sleeve positioned in the cover. Both sleeves have openings that are coaxial with the conveying line.

Claims

1. A device for administering powdered substances into deep-seated cavities of an organism, said device comprising a sprayer having a cylinder and a piston movable within said cylinder;

a catheter in said conveying line, arranged coaxially inside said drainage pipe and adapted to be introduced into a deep-seated cavity of an organism for spraying a powdered substance thereinside;

a hollow cylindrical body connected at one end to said sprayer;

a diametral partition dividing said hollow body;

a cover adapted to close said hollow cylindrical body at an end opposite to said one end;

a first sleeve having an opening and positioned in said diametral partition such that said opening is coaxial with said conveying line;

said first sleeve receiving an end of said catheter and connecting it to said sprayer;

a second sleeve having an opening and positioned in said cover coaxially with said opening of said first sleeve;

said second sleeve retaining said drainage pipe.
